[Note: I have no idea how much people have done on this already. It's
just that all this talk of automatic generation makes me curious.
Myself, I have no idea how VC makefile work.]
Is it so hard to automatically generate the necessary info? On a clean
source tree, "make -n" will dump all the commands required to complete
the build. You could probably extract all the info you required from
there, although the directory changing would kill you.
So my thought is, create a number of tracing scripts, eg cc-trace which
examine their arguments to see what needs to be done, recording the
current directory and such. Then execute:
make CC="cc-trace" LD="ld-trace" etc...
And you should be able to build up a tree of what depends on what. This
doesn't take care of the other stuff the makefile does though (like the
generation of pg_config_paths.h, can VC makefile do things like that?)
Have a nice day,
